Chapter 655: Is this coming to incorporate us?

Xu Qingzhou had already published his thesis proving the Riemann Hypothesis on arXiv, but it is different from the official announcement by the Clay Institute.

Publishing results can gain discussion in the academic community and can even gain 80% support from scholars, but intellectual property rights are still in a fuzzy state and can still be questioned as "partial verification, not a complete proof."

Personal disclosure is equivalent to issuing a declaration in the academic square, while Clay certification is like the Civilized Parliament promulgating a code of law.

The Clay Institute announcing Xu Qingzhou's results on its official website can be considered a true final conclusion, drawing a period at the end of the road to proving the Riemann Hypothesis.

It can be said that through Clay certification, the resolution of the Riemann Hypothesis can be upgraded from an "individual breakthrough" to a "civilizational axiom." Of course, this is a bit of an exaggeration; whether a mathematical truth is correct is not transferred by human will, nor does it rely on the endorsement of a research institute.

But it cannot be denied that the number of people questioning it will be reduced by more than 90%.

The internet is buzzing with discussion, and official media have forwarded the corresponding news.

Xu Qingzhou is not excited; life is routine, and he is buried in calculations.

Two days pass, the liveliness on the internet finally dissipates, and "Riemann Hypothesis Special Archives" have been established in the libraries of Jingda and MIT respectively.

In the office, however, Xu Qingzhou is staring at the manuscripts in front of him in a daze.

After he solved the problem that the violent thermal motion of ions leads to spin polarization decoherence, making it difficult to provide a stable carrier for the spin-locking effect, three technical difficulties appeared in the quantum spin-dynamic topological coupling model.

First point: the computational complexity of cross-scale modeling. The difference in spatiotemporal resolution between the phase-field method and topological optimization requires adaptive grids, leading to a 3-5 times increase in calculation time.

This is a piece of cake for the research institute's supercomputer.

Second point: the difficulty of experimental-model collaborative verification. Dynamic imaging of lithium deposition requires the combined use of synchrotron radiation XAS + cryo-electron microscopy. This is not a problem for Xu Qingzhou.

Don't forget, he spent over 100 million just to buy electron microscopes; capturing the dynamics of lithium deposition is a piece of cake.

Third point: the numerical instability of nonlinear systems, which might be the most thorny problem.

In nonlinear coupling terms, such as the superposition of double-well potential and SIMP penalty factors, the condition number of the Jacobian matrix suddenly increases to (>10^{12}), causing the iterative trajectory to deviate from the true solution.

To put it figuratively, it's like a roller coaster losing control and going off the tracks at a sharp turn, or a loose thread causing the entire piece of fabric to disintegrate while weaving.

Assistant Wang Sidong knocks on the door and enters.

"Professor, this is the construction plan for the compact magnet system sent over by Academician Ren."

Wang Sidong hands over a document.

"Good."

Xu Qingzhou nods.

Wang Sidong asks considerately: "Would you like a cup of coffee?"

"Iced Americano."

Xu Qingzhou thinks for a moment and still asks for a cup of coffee to refresh himself.

"Okay, coming right up."

Wang Sidong's efficiency is very high, and two minutes later, he brings the coffee over.

Xu Qingzhou sips the coffee and continues to flip through the plan sent over by Zhao Shengwen.

Currently, the fusion group has two tasks: one is to build a compact magnet system, and the other is to test the performance of superconducting thin films in extreme environments.

"A single set of compact magnets requires at least 300m of experimental space, including the winding area, testing area, storage area..." Xu Qingzhou flips through the blueprints and related equipment information.

The experimental site is chosen in the southwest of the research institute, close to the direction of the Summer Palace, and close to the No. 3 experimental building that has the superconducting thin film deposition system.

Previously, the working performance of superconducting thin films in extreme environments was simulated, but it ultimately relied on mathematical reasoning. The first task of controllable nuclear fusion is to start the verification of the extreme working conditions of superconducting thin film materials in May, using a 1MeV-class ion beam device for equivalent neutron irradiation verification, covering the 10n/cm flux simulation of the fusion reactor.
